PROTECTII IVE DEVICE FOR BANK CASHIERS R 'IIEIIZJZIERSv WINDOWS r f Application fiia 'Jiu 'e, 1930? S eriaI Nb. 465662;

This invention relates toprotective devices and a has special reference to a cashiers or tellers window protector.

One"mportant object of the invention is 5 tjo'improvethe general construction of devices or thisbharacter'. v i

Aseco"nd'important obj ect of the invention is to provide an improved opera-ting mecham nismi orf'devices ofthis character. I,

I A"'t.hird important object of the invention is to" provide, in such apparatus, animpi oved arrangement having folding .side wings toprote'ct the person behind the window from lateral attack. x

LA fourth important object oftheinven- {tion is to provide improved means for operatinathese wings. a 1

RVith the above andotherobjects in View,

the'invention consistsin general of certain novel details of construction andcombinations of parts hereinafter more fully described,- illustrated in the accompanying drawings and specifically claimed. In the drawings 7 A Figure 1 is-a rear-or insi'de elevati'on of such. a window, showing 'thedevice in connection therewith in-its housed position; c .Figure 2 is a section on the line- 22 of Figure 3 is a View similartdFigure'l but with the protecting device raised; Figure t is a section on the line 4-4: of Figure 3 'lfigureb is a section on the=line 5+5 of -Fi gure3; v v V Figure '6 is an: enlarged detail elevation partly in section and showing the spring means used toraise thelshield to operative o, position. 7

In the embodiment ofthe invention'as here shown, it has been illustrated as being applied to a bank counter 10 having a screen 11 at its 'front which is provided with a window openin 12 covered in part by 'the usual grill13L 1 5 is" a pair of tubes "ldl-ocated "at opposite hated the windowfandbpen at their upper ends; 1 The confronting sidesof these tubes are provided with longitudinally extending slots 17an'd ineach*tube is a head or plunger xte nding from the shield l t to the floor 18 'between'which'andthe floor is a'coiled compression spring 19 urging the plunger upwardly. These plungers are connected by the lower edge of a guardscreen 20 made of bullet proof'material and working in a slot 21 formed in" the shelf 14.- The lateral edges of this guard screen work in the slots 17 and hinged to these lateral edges are side guards 22 which are normally folded against the rear :face jofthe guard. 20 but which are urged to open position by springs .23. The rear edge o'fueach slot 17- is curved to forma cam 24: and then extends vertically to form a'stop 25. Secured to the loweredge of the screenQO and depending therefrom is aratchet bar 26 having on its .rear face upwardly facin ratchet teetlrwhich are engaged by a dog 21 sliding through guides 28and normallyheld in engagement with the teeth by a spring 29. A bell cranktreadle'SO has one arm con- '39 inected'tothe rear end'oii this dog '27 and its othei-"endentending rearwardly and upwardly convenient to the foot of'the personbehind thewindow. ii

Alsorthe bar 26nis provided with rack teeth 7 -31 on; one side and these teeth are engaged byagear 32 mounted on a rearwardly extend 'ing shaft 33 carrying an operating crank '34. The plungers or hea'dsil8 are carried on stems 35 whichproj'ect down through suitable opentings in'the bottoms of the cylinders 16 so that these-headsare properly guided in their move- ;nien ts; a r

The shaft 38 is supported in swinging bearings 36-so thatin using the gearh32'to .Ea'ctuate the latch bar, the: gear may be swung into, engagement with the :rack teeth but,

afterfthe screen-has been lowered, the gear mayche swung out of such engagement-s0 as not to interfere with "rapid upwardr'move- -ment ofth'e'screen. When out of engagement the shaft 33 is supported by a keeper 37.

- i In operation, the screen is normally .lowered'as shown in Figs. -1 and 2 and the 'dog 27 is engaged with the ratchet bar to hold the screen in this position against the action of the springs'19. In the event of an attack screen nears its upper position, the cam sur- Thus when the screen is down and the dog engaged, it will be held ready for use another time,

There has 7 thus been provided a simple i and efficient device of the kind described and,

for the purpose specified.

It is obvious that changes may be made in the form and construction of the invention without departing from the principles thereof. It i s not. therefore. desired to confine the invention to the exact formherein shown and described. but it is desired to include all such as come within the scope claimed.

I' claim L V 1. The combination with awindow opening; of a guard screen therefor normally held below said window opening, wings hinged to the lateral edges of the screen and normally folded thereagainst, springs urging said screen upwardly. to a position behind the window opening, a releasable dog holding said screen downwardly against the action of the springs, tubes surrounding said springs and. slotted to rece ve the'hinged edges of the screen and wings, the slots in the tubes form'- ing cams at their upper ends to control the movement of the wings in unfolding and folding, and springs connecting said screen and w ngs and urging the wings open.

2. The comb nation with a window opening: of a guard screen therefor normally held below said w ndow opening, wings hinged to the lateral edges'of thescreen'and normally folded thereagainst, springs urging said screen upwardly to a position behind the window opening. a releasable dog holding said screen downwardly agalnst the action of the springs, tubes surrounding said springs and slotted to receive the hlnged edges of the screen and wings, the slots inthe tubes forming cams at their upper ends to control the movement of the-wings in unfoldingand folding, springs connecting said screen and.
